Perhaps you should try some spelling variations:
decrease walking » increase walking (Expand search), decrease during (Expand search), decrease lodging (Expand search)
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
walking process » making process (Expand search), working process (Expand search), baking process (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease OR decrease walking process ) OR ( decrease lesions decrease at decrease ))~.
